Abstract: The new solutions of the parabolic equation describing vectorial Cartesian paraxial TM Gaussian light beams with complex astigmatism are investigated. The admissible values of the free parameters at which Gaussian beams carry finite power are established. The explicit expressions describing energy and polarization properties of vector Gaussian light beams with complex astigmatism are proposed. The graphical modeling and corresponding analysis of polarization ellipses, intensity and transverse energy fluxes of vector Gaussian paraxial light beams with homogeneous and inhomogeneous (TM-modes) polarization are performed.

Keywords: polarization, vector beams, Gauss beams, complex astigmatism, TM-modes, transverse energy fluxes.
